But we had tarried too long at our bread and cheese.
When we came to where the street leading to the Square of Saint Jacques joined the street that led in turn to the Brussels road, all the people there were crouching in their doorways as quiet as so many mice, all looking in the direction in which we hoped to go, all pointing with their hands.

No one spoke, but the scuffle of wooden-shod feet on the flags made a sliding, slithering sound, which someway carried a message of warning more forcible than any shouted word or sudden shriek.
We looked where their fingers aimed, and, as we looked, a hundred feet away through a cloud of dust a company of German foot soldiers swung across an open grassplot, where a little triangular park was, and straightened out down the road to Brussels, singing snatches of a German marching song as they went.
And behind them came trim officers on handsome, high-headed horses, and more infantry; then a bicycle squad; then cavalry, and then a light battery, bumping along over the rutted stones, with white dust blowing back from under its wheels in scrolls and pennons.
Then a troop of Uhlans came, with nodding lances, following close behind the guns; and at sight of them a few men and women, clustered at the door of a little wine shop calling itself the Belgian Lion, began to hiss and mutter, for among these people, as we knew already, the Uhlans had a hard name.
At that a noncommissioned officer--a big man with a neck on him like a bison and a red, broad, menacing face--turned in his saddle and dropped the muzzle of his black automatic on them.

They sucked their hisses back down their frightened gullets so swiftly that the exertion well-nigh choked them, and shrank flat against the wall; and, for all the sound that came from them until he had holstered his hardware and trotted on, they might have been dead men and women.
Just then, from perhaps half a mile on ahead, a sharp clatter of rifle fire sounded--pop! pop! pop!--and then a rattling volley.

We saw the Uhlans snatch out their carbines and gallop forward past the battery into the dust curtain.

And as it swallowed them up we, who had come in a taxicab looking for the war, knew that we had found it; and knew, too, that our chances of ever seeing that taxicab again were most exceeding small.
We had one hope--that this might merely be a reconnaissance in force, and that when it turned back or turned aside we might yet slip through and make for Brussels afoot.
